Merge branch '247-dagger-2' into 'master'

247 dagger 2

This MR in a nutshell replaces Guice and Roboguice with Dagger 2, which offers a lot more possibilities than is implemented in this branch, such as using lazy injections for performance purposes. With Dagger 2 all the magic happens at compile time, so no need to worry about unfulfilled injections at runtime, but due to restrictions I was forced to put injected test code into an Android module. We therefore have a new test module, `android-test`.

A consequence of using Dagger 2 is that we no longer have a view injector and I therefore had to replace those with manual references. 

Closes #247
